SPECIFICATION forming part of Letters Patent No. 659,177, dated October2, 1900.

Application iiled July 25, 1900. Serial No. 24.855. KNO model.)

lo all whom, it may concern:

Beit known that I, HENRY E. MooMAW, a citizen of the United States, anda resident of Salem, county of Roanoke, State of Virginia, have inventedcertain new and useful Improvements in Metallic Shingles, of which thefollowing is a full, clear, and eXact specification, reference being hadtherein to the accompanying drawings, in which- Figure l is a plan viewshowing several shingles interlocked; Fig. 2, a transverse sectionalView of the interlocked side edges of two adjoining shingles; Fig. 3, asimilar sectional View of one edge of one shingle; and Figa a viewsimilar to Fig. 2, showing a slight modification.

The objects of the invention are to provide a metallic shingle with aside lock which will permit the side edges of adjoining shingles to bereadily intel-locked and to so construct this side lock that it forms aseal which at all times effectually prevents the entrance of water orwind between the shingles and the roof and on which the expansion andcontraction of the shingles have no detrimental elfect.

Referning to the various parts by numerals, 1 designates a metallicshingle whose longitudinal side edges 2 and 3 are formed to interlockwith opposite edges of adjoining shingles. Near the edges 2 the metal ofthe shingle is bent upward, as at 4c, and from the upper edge of thisportion it is bent outward and downward and then folded under uponitself to form the longitudinal sealing-flange 5, whose under side formsa sealing-surface which inclines outward and downward. From theinne'redge of the under side of this ange the metal is bent downward and thenoutward to form the bottom of the channel or gutter '7,

and at the outer edge ot this gutter the metal,

is extended upward vertically to form the outer wall 8 of the gutter,said wall forming a stop which prevents the lateral separation of theshingles during the expansion or contraction thereof. From the top ofthis wall or stop 8 the metal is inclined downward and outward to formthe cam-surface 9, and from the lower edge of this cam the nailing-stripextends outward.

Near the edge 3 of the shingle the metal is inclined upward and outwardto form the cam l1, and from the upper edge of this cam it is bentdownward to form the stop 12. From the lower edge of this stop the metalis extended laterally a short distance and is then extended upward andoutward to form the inclined sealing-flange 13. The sealingflanges 5 and13 and the cam-surfaces 9 and ll all have the same degree of inclinationfor a purpose which will be hereinafter set forth.

To interlock the edges of adjoining'shingles, the flange 13 of oneshingle is passed into the channel 7 of the adjoining shingle and thenbrought up under the sealing-ange 5 either by forcing it into thechannel edgewise 0r by sliding it endwise therein, as may be founddesirable. When these edges are interlocked, the upper surface of thesealing-flange 13 will closely engage t-he under surface of thesealing-ange 5 and the Linder surface of cam 11 will fit down closely onthe inclined cam 9 and the stops 8 and 12 will be in position to engageeach other and prevent the lateral separation of the shingles. As thesealing-anges are of the same degree of inclination,the joint betweenthe shingles will be eifectually sealed against the entrance of water.The stop 8 forms a seal which prevents water, which, by reason of anydefect in the sealing-danges, may get into the gutter under the wall13,from passing under the shingles. As the cams 9 and 11 are of the samedegree of inclination as the sealing-flanges, they will maintain saidflanges in close contact during any lateral movement due to theexpansion or contraction of the shingles.

The upper ends of the sealing-flanges 13 and 5 may be higher than thetop of the stop or wall 12, as shown in Fig. Il, in order that shouldwater ll the glitter formed by the wall 12 and anges 13 and 5 it willoverflow wall 8 and run back on the shingle and will not overflow iange13.

The upper end of each shingle is provided with a suitable number oftransverse ridges which prevent water from passing up over the upperends of the shingles, and the lower edges of the shingles are bentdownward in the usual way to prevent water passing up under them. Theupper surface of each shingle is pressed upward to form a series ofcurved convex ribs which extend longitudinally of the shingle and arearranged in a U -shaped panel which is nearly equal in area to theexposed surface of the shingle. These ribs are narrow at their upperends and widen toward their lower ends, the sides of the center ribcurving outward toward the adjacent sides of the shingle and the sidesof the other ribs curving outward in substantially the same direction asthe adjacent side of the center rib. Narrow grooves are formed betweenthe ribs to offset said ribs from each other, and the lower ends of theribs are beveled off, the whole arrangement giving to the greaterportion of the shingle the appearance of a scalloped shell havingconveXed tapering ribs. The object of this construction is to divide theWater into numerous small streams and to so direct these streams as tosecure a uniform distribution of water over the roof without in any wayretarding the downward iiow of the water. As will be noted, there arefor the water.

A sheet-metal shingle raised and folded l near one longitudinal edge toform the longitudinal folded sealing-flange 5, inclining downward towardthe adjacent edge of the sheet, and having another raised portionbetween said sealing-flange and the adjacent edge ot` the sheet, thisraised portion constituting a longitudinal stop-wall 8 and alongitudinal cam-surface 9, and having near its opposite edge a raisedportion forming a longitudinal stop-Wall 12 and a cam portion l1 and atits extreme edge an upward and outward inclined sealing-flange 13, saidsealing-Hanges and cam-surfaces all having similar angles, as and forthe purpose set forth.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 20th day of July, 1900.
